Abstract
A találmány tárgya eljárás difenil-metán sorozatbeli poliaminokelőállítására, valamint eljárás difenil-metán sorozatbeli, csökkentettszínszámú poliizocianátok előállítására a megfelelő difenil-metánsorozatbeli poliaminok és foszgén reagáltatása útján. A csökkentettszínszámú poliizocianátokat úgy állítják elő, hogy a) anilint ésformaldehidet savas katalizátor jelenlétében poliaminná reagáltatnak,majd b) a reakcióelegyet 110 °C feletti hőmérsékleten bázissalsemlegesítik vagy a reakcióelegyet bázissal történt semlegesítése után110°C feletti hőmérsékletre melegítik, majd c) a poliamintfoszgénezéssel a megfelelő poliizocianáttal alakítják.
